Job description

EMCD is a leading technology company in the crypto industry, best known as the largest mining pool in Eastern Europe. We are expanding globally and building a comprehensive ecosystem of crypto services, including payment infrastructure, custody, mining solutions and enterprise-grade tools for businesses and institutions. We are looking for an experienced Senior Go Developer to own the blockchain rails that move user funds across our ecosystem.

• Develop and maintain blockchain rail services: deposits, withdrawals, address management and node interaction.
• Integrate new networks and coins end to end, from analysis to production, covering nodes, address derivation, precision, fees and confirmations.
• Own the ledger layer: entries, balances, holds, and reconciliation between on-chain data and internal accounting.
• Take full ownership of the deposit and withdrawal rails, including incidents such as uncredited deposits, stuck or duplicate withdrawals and refunds: investigate them using production and on-chain data, then fix the root causes.
• Contribute to design sessions, write HLDs and ADRs, and break work down into clear tasks.
• Review code, mentor teammates and take part in the team's on-call rotation.
• 5+ years of commercial Go development in production.
• Hands-on experience with blockchains, covering both the UTXO model (BTC and its forks) and the account model (EVM, TRON): node RPC, confirmations, reorgs, fees and mempool.
• Solid understanding of keys and addresses: HD derivation (BIP32/44), address formats and transaction signing.
• Experience with ledger and double-entry accounting: entries, holds (authorize capture/void), balance invariants and reconciliation.
• Strong grasp of reliability when handling money: idempotency, double-spend protection, the outbox pattern, at-least-once delivery with deduplication, and eventual consistency.
• PostgreSQL expertise: transactions, locking and isolation levels.
• Distributed systems experience with gRPC and RabbitMQ or Kafka.
• Working knowledge of Kubernetes and the monitoring stack (Prometheus, Grafana).
• Practical use of AI tools such as Claude Code or Cursor to speed up onboarding and development.
• Ability to write clear HLDs and ADRs and well-structured Jira tasks rather than one-liners.
• Proactive communication in cross-team threads and calls, with clear ownership of your scope.
• Working English for documentation and written communication.
• Remote-first company: work from anywhere in the world.
• Fully flexible working hours.
• Extended time off: 20 paid vacation days plus 12 bonus days per year.
• 100% paid sick leave.
• Professional growth support: courses, certifications and training programs.
• Real impact and ownership in fintech and crypto projects.
• Corporate benefits: EMCD product discounts and mining infrastructure access.
